Double-Acting Mechanical Seals

Mechanical Seals for Zero-Leakage and Challenging Requirements

Double-acting liquid-lubricated mechanical seals are the most common type for mixing applications. These seals can be used under nearly all operating conditions in a mixing vessel. They can also be designed as a gas-lubricated version in which a continuous supply of gas into the seal chamber maintains a marginal gap, thus preventing wear of the seal rings.
